    Hello
    Finished my LS2 install using a Corvette front end assembly. Got about 500 miles on it and seem to have a power steering leak from the cap after a long drive. Read a lot of posts that talk about pressure, flow and too much heat, didn't find any clear resolution. I'm running a stock 73 Camaro box with a quick turn ratio and the 02 Corvette style pump.

    Any insight would be greatly appreciated.
    Thanks

    Did you overfill it for one ? Snd just how much fluid do you lose ?

    Thanks for the replyr
    Didn't overfill it, seems to just be enough to drop on the belt and get distributed around to make a mess.
    It was warm out and I did about a 50 mile drive and was getting on it a bit. Was wondering if the higher rpms had something to do with it.

    Talked to the guys at Turnone yesterday, instead of trying to sell me something, they suggested a few things that I'm going to try.
    1. Bleeding the system again
    2. Monitor the temp of the fluid, should be 275 or less.
    3. Maybe try a PS fluid cooler if my temp is high.

    Good people there, not trying to sell you something you may not need.

    Using PS fluid or ATF? ATF is more tolerant of heat. Was this a new, rebuilt, or used pump. You can also use baby powder or fluorescent dye to verify origin of the leak.

    And if you do add a cooler .use the low pressure side. Less prone to leakage. I did one on my 1979 Z-28 RS using AN fittings and braided line.

    I can't remember the numbers, but there is some incompatibility between stock steering gear box and the corvette steering pump. I ended up using one of these borgeson reducer kits on my pump to be safe. https://www.summitracing.com/parts/...YmjtD_MfE2_2_BGRko35F7ELrQCBx_EIaAhMhEALw_wcB

    Do some research on that if nothing else pans out....also if you have a smaller pulley on the pump than stock, that can make the pump put out more pressure

    Thank you for all the replies, been out out of town that last few days..


    - I'm running PS fluid, synthetic...
    - It was used pump that came with the FE assembly I picked up..

    1971 Camaro guy, I was looking at that kit, did you install all the spacers/washers as others have mentioned, is the feel of your steering still pretty good? Mine feels like it did with the small block pump, no jitter, easy steer or anything..

    Hey all
    Thought I'd close the loop on this, bled the air out of the system and haven't had any issues since.
    Thanks for the help.
